New features in 16.04 LTS

Though we already know that this new release is not bringing a big UI changes to Unity Desktop.. It's worth to mention.. that ... Ubuntu 16.04 finally lets you move the Unity launcher to the bottom of the screen - nearly six long years after user's first asked. And you have the Ubuntu Kylin team to thank for it for it is they who did the heavy work of hacking Unity to be moveable.

While the 'option' to change position is buried deep in the geeky depths of dconf-editor it is the one change that everyone is talking about.But it's not the only welcome improvement.

Updated Packages

As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian's unstable branch; others have been explicitly pulled in for Ubuntu 16.04.

Linux kernel 4.4

This beta of Xenial ships with Linux kernel 4.4, with the following highlights:

Improved Intel Skylake processor support

3D support in the virtual GPU driver

New driver for Corsair Vengeance K90

Support for TPM 2.0 chips

Journaled RAID 5 support

Linux Kernel 4.4 also includes less obvious changes including bug fixes and improvements for various file systems, power efficiency, and memory management.

Core Application Updates

A batch of updates to Ubuntu applications are also included. Among them you'll find:

Known issues

As is to be expected, with any release, there are some significant known bugs that users may run into with this release of Ubuntu 16.04. The ones we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again:

Boot, installation and post-install

Errors about swap partition at install

There is a known issue regarding the creation of swap space during the install. In some cases the install will display the error message "Creation of swap space in Partition #n .... failed.". Please see this https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1552539 for more information. You may work around the issue by manually partitioning the disk and removing any existing swap partitions before then creating a new one.

Upgrade

14.04 LTS to 16.04 LTS Desktop Upgrade

There is a known issue which prevents the upgrade of 14.04 LTS to 16.04 LTS. Please see this bug for more information.
At this time you should not attempt to upgrade a production desktop from 14.04 LTS to 16.04 LTS.

Amazingly, there is only one known major bug in the release. Conrad explains, "in some cases, attempts to install to a hard drive that already contains a swap partition may fail in the partitioning phase. If you encounter this, the simplest workaround is to boot to the live session, start a terminal (Ctrl-Alt-T) and type 'sudo swapoff -a'. You can then start the installation from the icon on the desktop and it should proceed successfully".

Graphics and Display

fglrx

The fglrx driver is now deprecated in 16.04, and we recommend its open source alternatives (radeon and amdgpu). AMD put a lot of work into the drivers, and we backported kernel code from Linux 4.5 to provide a better experience.
When upgrading to Ubuntu 16.04 from a previous release, both the fglrx driver and the xorg.conf will be removed, so that the system is set to use either the amdgpu driver or the radeon driver (depending on the available hardware).

Download Ubuntu 16.04 Beta 2

Beta releases of Ubuntu are not for everyone. If you need a stable system, hate bugs and can’t deal with potential package breakages, wait for the stable release next month.
And if you are keen to try it out stick to running it off of a live USB or DVD. Also note that there is a major bug that may cause beta installs to fail on hard-drives which already contain a swap partition.
